有一些问题，没有找到解决方案。问题是，我有一个位于布局上的图像视图，而此布局位于窗口管理器上，该图像视图是可单击的。该图像视图必须左右移动并可以单击。这是我的代码
公共类FloatingAnimationService扩展了服务{
private WindowManager windowManager;
private ImageView floatingUnit;
private boolean isClicked;
public void onCreate() {
super.onCreate();
isClicked = false;
floatingUnit = new ImageView(this);
//a unit as imageView

}
}
}.start();
}

请帮忙。谢谢 ！
最佳答案
谢谢大家。自己找到解决方案。诀窍是：要移动放置在窗口管理器上的图像，必须更新布局参数。
这是下面的代码
private void startAnimationTimer(final View floatingUnitLayout) {
long animationLifeTime = AppData.first(AppData.class).getCountSecondsPicShow();
countDownTimer = new CountDownTimer(animationLifeTime, 100) {
public void onTick(long millisUntilFinished) {
Log.i("animation remaining: ", Long.toString(millisUntilFinished / 1000));
myParams.x = myParams.x + 2;
myParams.y = myParams.y + 2;
windowManager.updateViewLayout(floatingUnitLayout, myParams);
}
public void onFinish() {
Log.i("animation: ", "DONE");
if (!isClicked) {
windowManager.removeViewImmediate(floatingUnitLayout);
stopSelf();
}
}
}.start();
}
